SPECIFICATION forming part of Letters Patent No. 768,181, dated August23, 1904. Application filed April 27, 1904. Serial No. 205,178. on)model.)

To all whom/it may concern:

Be it known that I, SYLvEs'rER R. JOHNSON, a citizen of the UnitedStates, residing at Winston, in the county of Daviess and State ofMissouri, have invented certain new and useful Improvements inRoad-Scrapers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to scrapers which will be found useful for a greatvariety of purposes, as in road-building, excavating earth,

&c.; and my invention consists of certain novel features ofcombinationand construction of parts the preferred form whereof will be hereinafterclearly set forth, and pointed out in the claim.

The main object of my invention, among others, is to provide a machineof the character specified which will be found reliably eflicient inscraping up the earth and moving it to a point desired, as inroad-building.

A further object of my invention is to place the scraper-blade under thecomplete control of the operator, whereby it may be elevated,

ous details of my invention and cooperating accessories numerals will beemployed, the same numeral applying to a similar part throughout theseveral views. I

0 Referring to the numerals on the drawings, 1 designates thecarrying-wheels, which may be of any preferred construction or .may bethe wheels ordinarily employed upon a mowing machine, thus enabling thefarmer to readily improvise a good part of the machine right at his ownhome.

2 designates the carrying-axle, upon which the platform 3 is secured inany preferred way, whilethe draft-tongue 1 is attached to the centralportion of said axle or platform 3 and to which the draft-animals areattached in the usual manner. The platform 3 extends rearwardlysufficiently to afforda point of attachment for the standard 5, uponwhich the seat'6 i'slocated. The scraper-blade 7 is connected With theaxle by means of the rearwardly-directed beams 8 and 9, the rear ends ofsaid beams being curved downward substantially as inthe formation of aplow-beam,

and the scraper-plate is secured to said downwardly-directed ends in anypreferred way,

as by the bolts 10 or equivalent thereof.

It will be understood that the forward ends of thebeams 8 and 9 are soconnected to the carrying-axle 2, as by bending the forward ends in themanner indicated by the numeral 11, whereby they will be held inengagement with the aXleQ by the bolt 12. This method of connecting theforward ends of the beams 8 and 9 to the axle will, it is obvious, admitthe scraper-blade to be raised and lowered as desired, and in order toaccomplish the raising and lowering of said beams and the scraper-bladecarried thereby I provide the on the rear 'end of the platform 3 bymeans of the" bolt or rod 15, a suitable rack-bar 16 being provided witha-plurality of notches or recesses adapted to cooperatewith the lip 17upon a contiguous part of the controlling-lever. The angular extension 1L is bent back updn itself at its extreme outer end, as indicated by thenumeral 18, said hook-like terminal 18 being designed to engagethe baror loop member 19, secured to theupper edge of the middle section ofthe-scraper-blade, as

clearly shown in Fig. 1,andit is therefore obviousthat by moving thecontrolling-lever forward the scraper-bladeand the beams 8 thescraper-blade at an oblique angle relative to the plane of thecarrying-axle, whereby the scraper'blade will deliver the earth engagedthereby and discharge it at its rear end, as is very desirable inroad-building. I have also provided an attachment, which I havedesignated by the numeral 20, which is formed with the two lugs 21 and22, said lugs being designed to take into suitable apertures formed nearthe end of the scraper-blade and be secured thereon by suitable nuts 28,the forward end of the member 20 being also provided with an aperture 2L, by which it may be attached to the side of the beam 9.

If desired, one or more of the apertures 24: may be formed so that byentering suitable bolts 25 therethrough and through registering holesprovided in the beam 9 it is obvious that the auxiliary scraper 20 maybe reliably held in place, so that a heavy load of earth may be drawn toany point desired and quickly discharged by a forward movement of thecontrolling-lever 13.

i The various parts of my invention may be cheaply and expeditiouslymanufactured and made of any suitable material and any desired size, andWhile I have described the preferred combination and construction ofparts I wish to comprehend in this application all substantialequivalents and substitutes which may be considered as falling fairlywithin the scope of my invention.

Believing that the advantages and manner of using my combined scraperand earth-carrying machine have thus been made clearly apparent, furtherdescription is deemed unnecessary.

What I claim as new, and desire to secure by Letters Patent, is

The herein-described combined scraper and earth-carrier comprising asuitable carryingframe; a platform and seat erected thereon; ascraper-blade disposed at an oblique angle to the plane of thecarrying-axle; a controlling-lever for said blade and an auxiliaryscraper-blade connected to the end of the main scraper-blade and to thecarrying-Man1 therefor whereby a load of earth may be gathered and drawnto a point desired and readily discharged all combined substantially asspecified and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
